The Sony a7S is the third camera in Sony’s a7 series and this write-up is the third installment in my series testing various rangefinder lenses on this platform to determine technical performance when photographing a distant, near infinity scene. While this may seem a simple task, the combination of a rangefinder lens with a short exit pupil distance and a scene at infinity is the most technically demanding combination of variables influencing technical image quality from these ‘mirrorless’ cameras. Please refer to the original a7 shootout for an explanation why infinity focus is such a ‘torture test’ for these cameras.

As a bonus comparison, I photographed the same scene on the same day, with the same lenses, using the Leica M Typ240 camera.

As a follow-up to my overwhelmingly popular October 2013 infinity test with a preproduction Sony a7 and various rangefinder lenses, here’s the infinity shootout I really wanted to do back then… between a regular production Sony a7R and Leica M9, with a similar, though not identical, collection of a couple dozen mostly rangefinder lenses… Unfortunately, this time I’m not one of the first in the world with the results! Please refer to the a7 shootout for an explanation why infinity focus is such a ‘torture test’ for these lenses and cameras.
